Time slows for an object that accelerates and/or decelerates. This is the answer to, say, the twin paradox. Why does the traveling twin stay young? Becouse he leaves, turns back and stops at home while the other twin stays at Earth all the time.
Well, what is the difference between energy's matter form and energy form? It has been suggested that the properties of mass are caused by a particle called Higgs' boson. This particle would cause the inertia. Could it also be the fundamental reason to gravity? I suppose it could. Actually, I...
If you place a mass in the sheet, the sheet bends all right. And in the process of bending it also stretches. Now if you put a mass in space, it bends the space in its fourth dimension (space dimension, no need to get involved with time). And when the space bends, it also stretches, but in the...
Well, good if there are no singularities in mathematical sense. But i referred to singularity as a condition, where mass density is infinite. And then i wrote my opinion of the subject, why cannot such a thing take place? Answer was simplifiedly this: when the outer volume of a piece is mass is...
No, just the direction would alter. But negative energies (or masses) have never been measured, and thus the question is only theoretical. And notice this: if we had a piece with negative mass, and another similar, they would attract to each other the same way the two positive masses do...
All right, physicists claim that mass can be at infinite density. This condition is called the singularity, an one-dimensional point that is having mass (or energy, whatever)inside it.
I say mass cannot possibly form singularities. Why? Because of the following:
When there is mass inside...
